Use the DISPLAY WORK operator command to display
classification
information. Use this command to determine if your classification
scheme is classifying the work as you intended. Issue the
following command to display the IIOP, HTTP, INTERNAL, SIP, MDB, and
optimized local adapter classification information:MODIFY|F <servername>,DISPLAY,WORK,CLINFO
Issue
this command against each application server. The
following example shows a possible result of issuing the new operator
command:

- An explanation of the command output:
- BBOJ0129I: The file workload
classification file was loaded at time.
- The message indicates the workload classification file currently
active and the time that it was loaded.

CLASSIFICATION COUNTERS FOR type WORK
- The header message for messages that display the usage of the
workload classification rules. The value of type can
be HTTP, IIOP, INTERNAL, SIP, OLA,
or MDB.
- BBOO0282I
CHECKED n1, MATCHED n2,
USED n3, COST n4, DESC: text
- This message displays information about a particular rule in the
workload classification. This message displays the following information:
- n1 - The number of times the rule has been
examined.
- n2 - The number of times that
this rule has
been matched by the request.
- n3 - The number
of times that this rule has
been used.
- n4 - The cost of using the rule,
or the number
of compares that are required to determine if this rule is the correct
rule to use.
- text - The descriptive text
from the classification
rule so that you can tell which classification rule is being displayed.
- BBOO0283I FOR type WORK:
TOTAL
CLASSIFIED n1, WEIGHTED TOTAL COST n2
- This message shows the summary information for the IIOP, HTTP,
INTERNAL, SIP, MDB, or optimized local adapter work classification.
This message displays the following information:
- type -
The type of work that is being displayed.
The value must be IIOP, HTTP, INTERNAL, SIP, MDB, or OLA.
- n1 -
The number of requests that were classified
using the classification rules.
- n2 - The
weighted total cost, calculated by
taking the number of times that each rule was used multiplied by the
cost, or number of rule compares that were done, of using the rule
and adding those up across all the rules.
The total cost n2 divided
by the total number
of requests classified n1 equals the cost of using
the table. The closer that the value is to one, the lower the cost
of using the defined rules. A value of 1 indicates that there is just
the default classification, so no requests match it.
